DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter the present invention will be described in details with reference to the accompanying drawings and embodiments.

According to FIG. 1 and FIG. 2, the present invention includes an insole body. As shown in FIG. 3, said insole body has a pressure controller A located at its side. In this embodiment, as shown in FIG. 1 and FIG. 2, the two pressure controlling means include a multi-pipe circulating flow pressure controlling means 1 and a single-pipe bi-directional flow pressure controlling means 2, furthermore an adjusting device 3, which controls the startup of either one of said two pressure controlling means according to user's choice, is further installed between the two pressure controlling means.

Wherein, the multi-pipe circulating flow pressure controlling means 1 includes a ball valve 11 as the entry of the flow passage and a vane valve 12 as the exit of the flow passage. As shown in FIG. 2, a hinge 121 is set in the vane valve 12. The single-pipe bi-directional flow pressure controlling means 2 includes a ball valve 21 as the access of the flow passage. The adjusting device 3 is used to control the alternate opening or closing of the control units of the two pressure controlling means.

As shown in FIG. 2, the adjusting device 3 includes a rotation shaft 31 and an adjusting turnbutton 32 connected on the exterior bottom of said rotation shaft 31. The adjusting turnbutton 32 is fastened at the bottom outwardly with respect to the ball valve 11, and the adjusting turnbutton 32 is engaged with the rotation shaft 31 by screw threads. A concave 4 is set correspondingly for mounting the adjusting turnbutton 32. A leak resistant ring is set between the adjusting turnbutton 32 and the rotation shaft 31, and a cage nut 315 is set on the leak resistant ring 314. Disc-shaped adjusting heads 311 are sleeved on the middle part of said rotation shaft 31, and by moving said adjusting heads, the ball 111 of the ball valve 11 may be laterally displaced. A spring 313 is set below the lower disc-shaped adjusting head 311. An adjusting tip 312 is set on the interior top of said rotation shaft 31 so as to press against a ball 211 of the ball valve 21 and to make the ball 211 displace longitudinally. A spring 212 is set within the ball valve 21 so as to downwardly push against the ball 211.

In the present invention, the adjusting device 3 controls the opening or closing of the ball valve 11 of the multi-pipe circulating flow pressure controlling means 1 and the ball valve 21 of the single-pipe bi-directional flow pressure controlling means 2 alternately by a screw element. As shown in FIG. 1 and FIG. 2, the rotation shaft 31 is moved upwards by adjusting the turnbutton 32. And in the multi-pipe circulating flow pressure controlling means 1, the ball 111 is moved outwards till the ball valve 11 is closed. In the mean time, in the single-pipe bi-directional flow pressure controlling means 2, the ball 211 is pushed away from the access of the ball valve 21 by the adjusting tip 312, thereby, the single-pipe bi-directional flow pressure controlling means 2 is opened and the multi-pipe circulating flow pressure controlling means 1 is closed. In contrary, as shown in FIG. 1 and FIG. 2, the rotation shaft 31 is moved downwards by adjusting turnbutton 32. In the single-pipe bi-directional flow pressure controlling means 2, the ball 212 is moved downwards till it blocks the access of the ball valve 21. In the mean time, in the multi-pipe circulating flow pressure controlling means 1, the ball 111 returns toward the center, thereby, the ball valve 11 is opened, that is to say that the multi-pipe circulating flow pressure controlling means 1 is opened and the single-pipe bi-directional flow pressure controlling means 2 is closed. In such a way, the ball valves 11 and 21 are opened and closed alternately by adjusting turnbutton 32. It could be seen from the above that the adjusting device 3 controls the opening or closing of the control valves of the two kinds of pressure controlling modes by a screw element. In such a way, the present invention introduces a multi-pipe circulating flow pressure controlling mode by the multi-pipe circulating flow pressure controlling means 1 and a single-pipe bi-directional flow pressure controlling mode by the single-pipe bi-directional flow pressure controlling means 2, and one of said pressure controlling modes is selected to be opened or closed alternately by a screw element. The multi-pipe circulating flow pressure controlling means 1 or single-pipe bi-directional flow pressure controlling means 2 of the present invention could be a pressure controlling means for liquid or gas flow.

In practical use, the number of the disc-shaped adjusting heads 311 may be set corresponding to the number of the ball valves to be controlled.

In this embodiment are described in details the principle, structure and working process of the two pressure controlling modes adopted in the pressure controller A, namely the multi-pipe circulating flow pressure controlling mode and the single-pipe bi-directional flow pressure controlling mode. Similarly, the pressure controller A could adopt two different kinds or more than two kinds of pressure controlling modes as well. As for the principle and structure, they are same as or similar to the above description, which could be implemented by a technical person in this field without creative work.
